Reporting guidelines are structured tools developed using explicit methodology that specify the minimum information required by researchers when reporting a study. The use of artificial intelligence (AI) reporting guidelines that address potential sources of bias specific to studies involving AI interventions has the potential to improve the quality of AI studies, through improvements in their design and delivery, and the completeness and transparency of their reporting. With a number of guidance documents relating to AI studies emerging from different specialist societies, this Review article provides researchers with some key principles for selecting the most appropriate reporting guidelines for a study involving an AI intervention. As the main determinants of a high-quality study are contained within the methodology of the study design rather than the intervention, researchers are recommended to use reporting guidelines that are specific to the study design, and then supplement them with AI-specific guidance contained within available AI reporting guidelines.Invited for the cover of this issue are Dr. Stephen Butler, Dr. Hennie Valkenier and co-workers at Université Libre de Bruxelles, Loughborough University, Masaryk University, and the University of Bristol.

A-366 price One of the most prominent pathophysiological symptoms of MCT8-deficiency is hypomyelination. Here, patient-derived induced pluripotent stem cells (iPSCs) were used to study the role of MCT8 and TH on the maturation of oligodendrocytes. Interestingly, neither MCT8 mutations nor reduced TH affected the in vitro differentiation of control or MCT8-deficient iPSCs into oligodendrocytes. To assess whether patient-derived iPSC-derived oligodendrocyte progenitor cells (iOPCs) could provide myelinating oligodendrocytes in vivo, cells were transplanted into the shiverer mouse corpus callosum where they survived, migrated, and matured into myelinating oligodendrocytes, though the myelination efficiency was reduced compared with control cells. When MCT8-deficient and healthy control iOPCs were transplanted into a novel hypothyroid immunodeficient triple knockout mouse (tKO, mct8-/- ; oatp1c1-/- ; rag2-/- ), they failed to provide behavioral recovery and did not mature into oligodendrocytes in the hypothyroid corpus callosum, demonstrating the critical role of TH transport across brain barriers in oligodendrocyte maturation. We conclude that MCT8 plays a cell autonomous role in oligodendrocyte maturation and that functional TH transport into the central nervous system will be required for developing an effective treatment for MCT8-deficient patients.
Chronic Achilles tendon rupture is commonly defined as a rupture presenting 6 weeks after the time of injury and operative management is recommended. This research aims to describe a novel modified surgical technique in the repair of chronic Achilles tendon rupture and to report the result of this technique.

This is a retrospective study performed between January 2007 and January 2017, and a novel modification of El Shewy et al.'s surgical technique is described. Fifteen patients with chronic rupture of Achilles tendon repaired with the technique by a single experienced surgeon were identified. Patients were contacted via phone call and questionnaires completed. Achilles Tendon Rupture Score and pain score were assessed via questionnaires.

Thirteen patients were contacted and two patients were uncontactable. Ten patients were able to return to their premorbid level of function. Twelve patients were satisfied or very satisfied with the outcome. Only one patient was very dissatisfied with the outcome. The average Achilles Tendon Rupture score was 72 (n=7, 54%). The average pain score was 1.23 (n=13, 100%).

This novel modified surgical technique demonstrated good functional outcomes and high levels of patient satisfaction in patient with chronic Achilles tendon rupture. It can be considered in the repair of chronic Achilles tendon rupture.

Benign oesophageal strictures can have several aetiologies and often require serial endoscopic dilatation. The aim of this study was to review the existing literature regarding the efficacy of self-dilatation for benign oesophageal strictures.

This study presents the results of a systematic review that was performed on the available literature using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Full-text articles from Medline, PubMed and Embase were used, as well as associated reference lists. This study systematically reviews the literature to present the efficacy and different outcome measurements associated with self-dilatation of benign oesophageal strictures.

This study identified 13 articles with 274 participants.

Self-dilatation for refractory benign oesophageal strictures is effective regardless of aetiology. It is well tolerated, safe and leads to lasting symptom resolution in the majority of patients.

Previous connectome integration studies almost exclusively required predefined atlases. However, there are many potential atlases to choose from and this choice heavily affects all subsequent analyses. To avoid such an arbitrary choice, we propose a novel atlas-free approach, named Surface-Based Connectivity Integration (SBCI), to more accurately study the relationships between SC and FC throughout the intra-cortical gray matter. SBCI represents both SC and FC in a continuous manner on the white surface, avoiding the need for prespecified atlases. The continuous SC is represented as a probability density function and is smoothed for better facilitation of its integration with FC. To infer the relationship between SC and FC, three novel sets of SC-FC coupling (SFC) measures are derived. Using data from the Human Connectome Project, we introduce the high-quality SFC measures produced by SBCI and demonstrate the use of these measures to study sex differences in a cohort of young adults. Compared with atlas-based methods, this atlas-free framework produces more reproducible SFC features and shows greater predictive power in distinguishing biological sex. This opens promising new directions for all connectomics studies.
Development or progression of inflammation in neoplastic diseases is known to be part of the disease. Lymphocyte to C-reactive protein ratio (LCR) is a new indicator showing the inflammatory state. The aim of this study is to show the clinical importance of the relationship between the preoperative LCR and the prognosis of patients with gastric cancer.

We evaluated gastric cancer patients, who underwent surgery between 2010 and 2015. LCR and neutrophil-to-lymphocyte ratio (NLR) were calculated from pre-treatment of complete blood counts. Both ratios were compared to the perioperative outcomes and median survival times. Association between LCR and postoperative tumour stage was studied by using multivariate analysis with other clinicopathological variables.

A total of 123 patients were included. The mean age of the patients was 65.36± 10.08. Preoperative low LCR value was associated with advanced tumour stage, adjacent organ invasion, lymph node metastasis and postoperative early complications. The receiver operating characteristic analysis results showed that LCR and NLR parameters were significant (CI 0.718-0.886; 95%); P < 0.001, CI 0.534-0.732; 95%). Cut-off value being 193, the mean survival of patients who had LCR values of overcut-off value was found to be significantly higher compared with the patients with lower LCR values (P < 0.001).

LCR, a simple calculated ratio of values obtained from easy and widely available serum indicators could be an effective prognostic marker with gastric cancer.

This study aimed to describe the clinical outcomes of total pancreatectomy with islet autotransplantation (TP-IAT) in Australia.

Individuals selected for TP-IAT surgery according to the Minnesota Criteria (Appendix) without evidence of diabetes were evaluated including time to transplantation from pancreatectomy, islet numbers infused and post-transplantation HbA1c, C-peptide, total daily insulin and analgesic requirement.

Sixteen individuals underwent TP-IAT from Australia and New Zealand between 2010 and 2020. Two recipients are deceased. The median islet equivalents/kg infused was 4244 (interquartile range (IQR) 2290-7300). The median C-peptide 1 month post-TP-IAT was 384 (IQR 210-579) pmol/L and at median 29.5 (IQR 14.5-46.5) months from transplant was 395 (IQR 139-862) pmol/L. Insulin independence was achieved in eight of 15 (53.3%) surviving recipients. A higher islet equivalents transplanted was most strongly associated with the likelihood of insulin independence (P < 0.05). Of the 15 surviving recipients, 14 demonstrated substantial reduction in analgesic requirement.

The TP-IAT programme in Australia has been a successful new therapy for the management of individuals with chronic pancreatitis including hereditary forms refractory to medical treatment to improve pain management with 50% insulin independence rates.

Gestational weight gain (GWG) is increasingly monitored in the United States and Canada. While promoting healthy GWG offers benefits, there may be costs with over-surveillance. We aimed to explore these costs/benefits.

Quantitative data from 350 pregnant survey respondents and qualitative focus group data from 43 pregnant/post-partum and care-provider participants were collected in the Mothers to Babies (M2B) study in Hamilton, Canada. We report descriptive statistics and discussion themes on GWG trajectories, advice, knowledge, perceptions, and pregnancy diet. Relationships between GWG monitoring/normalization and worry, knowledge, diet quality, and sociodemographics-namely low-income and racialization-were assessed using χ
tests and a linear regression model and contextualized with focus group data.

Most survey respondents reported GWG outside recommended ranges but rejected the mid-20th century cultural norm of "eating for two"; many worried about gaining excessively. Conversely, respondents living in very low-income households were more likely to be gaining less than recommended GWG and to worry about gaining too little.
